[0032] The technical solutions in the embodiments of the present application will be apparently and completely described in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. The following description of at least one exemplary embodiment is actually only illustrative in nature, and by no means as any limitation on the present application and its application or use. Based on the embodiments in the present application, all other embodiments obtained by a person of ordinary skill in the art without any creative work fall within the scope of protection of the present application.

[0033] As shown in Figures 1 to 5, the embodiments of the present application provide a guide frame structure, which comprises a frame body 10 and a bent portion 20 arranged at the end of the frame body 10. The end of the frame body 10 has an end face and two side faces, the end face is located between the two side faces and sequentially connected along the peripheral direction of the frame body 10. The bent portion 20 comprises a reinforcing member 22 and a bent plate 21 arranged perpendicularly to the frame body 10. The bent plate 21 is an integral structure with the frame body 10 and formed at the end face of the frame body 10. The reinforcing member 22 is an integral structure with the bent plate 21 and formed at one side of the bent plate 21. The reinforcing member 22 is connected to one of the side faces of the frame body 10. It can be understood that the reinforcing member 22 is an integral structure with the bent plate 21 and formed at the side of the bent plate 21 facing one of the side faces of the frame body 10 (it can also be understood as the side of the bent plate 21 closest to one of the side faces of the frame body 10). The reinforcing member 22 is connected to the side face of the frame body 10 corresponding to the side.

[0034] In the present embodiment, the two side faces of the end of the frame body 10 are parallel to each other. The bent plate 21 is an integral structure with the frame body 10 and the reinforcing member 22 is an integral structure with the bent plate 21, which facilitates the integral molding of the guide frame structure, eliminates the need for separate processing of the reinforcing member 22 and additional installation, and is conducive to simplifying the installation process, saving installation costs and improving processing efficiency. Further, the reinforcing member 22 transmits and disperses the force of the frame body 10 by connecting the bent plate 21 and the frame body 10, which improves the connection strength between the bent plate 21 and the frame body 10, makes the connection position of the bent plate 21 and the frame body 10 less likely to deform or break, and further improves the bending resistance and impact resistance of the bent plate 21, which is conducive to ensuring the reliability and stability of the application of the guide frame structure.

[0035] Specifically, the frame body 10 and the bending part 20 in the embodiment are integrally formed by stamping and bending. Further, in order to ensure the reinforcing effect of the reinforcing part 22 on the connection strength between the bent plate 21 and the frame body 10, the reinforcing part 22 is fixedly connected with the side surface of the frame body 10 after being formed by bending, and the preferred connection mode is welding, so as to connect the reinforcing part 22 and the frame body 10 into an integrated body, thereby ensuring the deformation prevention or fracture prevention reinforcement of the bent plate 21.

[0036] In the first embodiment shown in FIGS. 1 and 2, the reinforcing part 22 is a rectangular plate structure in the shape of a triangle. In this way, the reinforcing part 22 is integrally formed by stamping and bending with the bent plate 21, and the reinforcing effect of the reinforcing part 22 on the connection strength between the bent plate 21 and the frame body 10 is ensured.

[0037] It can be understood that the shape of the reinforcing part 22 and the like can be adaptively adjusted according to actual conditions during forming. For example, in the second embodiment shown in FIGS. 3 to 5, the reinforcing part 22 is a rectangular plate structure in the shape of a rectangle. In other embodiments not shown in the drawings, the reinforcing part 22 is a frame-like plate structure in the shape of an L or a "mouth". In this way, the reinforcing part 22 is designed to be lightweight while ensuring the reinforcing effect of the reinforcing part 22 on the connection strength between the frame body and the bent plate 21. For example, in an embodiment, when the reinforcing part 22 is in the shape of an L, the L-shaped reinforcing part 22 has a first edge portion and a second edge portion arranged at a right angle. The first edge portion is connected with the bent plate 21, and the second edge portion is connected with the frame body 10, so as to reinforce the connection strength between the bent plate 21 and the frame body 10.

[0038] In the embodiment, the plate structure of the reinforcing part 22 is arranged perpendicularly to the frame body 10 and the bent plate 21, which is beneficial to ensure the transmission and dispersion effect of the stress on the frame body 10 and prevent stress concentration, so as to further ensure the reinforcing effect of the reinforcing part 22 on the connection strength between the frame body and the bent plate 21.

[0039] It can be understood that in other embodiments not shown in the drawings, the plate structure of the reinforcing part 22 can be arranged at an angle with the frame body 10 and / or at an angle with the bent plate 21, and is not limited to the perpendicular arrangement in the embodiment, which is not exemplified here.

[0040] Specifically, in the embodiment, the connection position of the reinforcing part 22 and the frame body 10 forms a first connection region, the connection position of the bent plate 21 and the frame body 10 forms a second connection region, and the first connection region and the second connection region are connected. In this way, the reinforcing effect of the reinforcing part 22 on the connection strength between the frame body and the bent plate 21 is ensured.

[0041] It can be understood that in other embodiments not shown in the figures, the first connecting region and the second connecting region are spaced apart to avoid interference or difficulty in bending at the transition of the reinforcing member 22, the frame body 10, and the bent plate 21.

[0042] In the first embodiment shown in Figures 1 and 2, the bent portion 20 further comprises a reinforcing rib 23 arranged at the connecting position of the bent plate 21 and the frame body 10. In this way, the reinforcing rib 23 further enhances the connection strength of the connecting position of the bent plate 21 and the frame body 10 (by about 20% or more), avoids deformation or breakage of the bent plate 21, and ensures the reliability and stability of the guide frame structure.

[0043] It can be understood that the arrangement of the reinforcing rib 23 in the first embodiment and the arrangement of the reinforcing rib 23 in the second embodiment can be as shown in the third embodiment of Figures 6 to 8, or the fourth embodiment shown in Figure 9, or the fifth embodiment shown in Figure 10.

[0044] In the third embodiment shown in Figures 6 to 8, two bent portions 20 are arranged at either end of the frame body 10, the two bent plates 21 at the same end of the frame body 10 have opposite bending directions, and the two reinforcing members 22 are connected to the two sides of the end of the frame body 10, respectively. In this way, the reliability of the guide frame structure in the application of the reversing valve is ensured.

[0045] It can be understood that the number of reinforcing ribs 23 can be adjusted to be multiple according to actual conditions, and the multiple reinforcing ribs 23 are arranged at intervals. For example, in the fourth embodiment shown in Figure 9, two reinforcing ribs 23 are arranged at the connecting position of the bent plate 21 and the frame body 10. In this way, the reliability of the connection strength enhancement of the connecting position of the bent plate 21 and the frame body 10 can be ensured according to actual conditions.

[0046] Specifically, the reinforcing rib 23 is stamped and formed on the inner side of the connecting position of the bent plate 21 and the frame body 10, and a stamping groove 24 is formed on the outer side of the connecting position of the bent plate 21 and the frame body 10. In this way, the processing difficulty of the reinforcing rib 23 is reduced, and the reinforcing rib 23 is quickly processed and formed.

[0047] In the present embodiment, the reinforcing rib 23 is a block structure with a triangular or triangular-like cross section, and the dimension of the reinforcing rib 23 in the width direction of the frame body 10 is 1.5mm-2.5mm. By limiting the minimum width of the reinforcing rib 23, the reliability of the connection strength enhancement is ensured, and the connection strength enhancement effect is not obvious due to too small width or the structural strength of the bent plate 21 is affected due to too large width, etc. It should be noted that the above-mentioned width range of the reinforcing rib 23 is a preferred range, which can be adaptively adjusted according to actual conditions.

[0048] It can be understood that, in the fifth embodiment shown in FIG. 10, the stamping height of the reinforcing rib 23 (which can also be understood as the depth of the stamping groove 24) can be adjusted according to actual conditions, as long as the inside is obviously convex and the minimum width of the reinforcing rib 23 is within the above range.

[0049] Another embodiment of the present application provides a reversing valve, which comprises the guide frame structure described above, and further comprises a valve body, a piston assembly and a slider, the guide frame structure is installed in the valve body, the slider is installed on the guide frame structure, and the piston assembly is connected to the frame body 10 through the bending plate 21 and can push the guide frame structure to move in the valve body. In this embodiment, the reinforcing member 22 and the reinforcing rib 23 are arranged to enhance the connection strength of the connection position of the bending plate 21 and the frame body 10, so as to avoid the frame body 10 being easily lifted up under the action of liquid impact during use of the reversing valve, thereby avoiding the connection position of the frame body 10 and the bending plate 21 where the piston assembly is located being easily deformed by yielding, and ensuring the reliability and stability of the reversing valve.

[0050] The above only describes the preferred embodiments of the present application and is not used to limit the present application. For those skilled in the art, the present application can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
